This shows active droplets. Droplets of filamentous material enclosed in a lipid membrane: these are the models of a "simplified" cell used by the SISSA physicists Luca Giomi and Antonio DeSimone, who simulated the spontaneous emergence of cell motility and division - that is, features of living material - in inanimate "objects". The research is one of the cover stories of the April 10th online issue of the journal Physical Review Letters.
